VAPOR-BURNER..

l SPECIFICATION forming part of Letters Patent No. 288,343, datedNovember 13,1883. l

` Application mea March 1-1, 1583. (No model.)

To all whom it mayeolwern: f Beit known that I, Ao cUs'r KINDERMANN,

State of Ohio, have invented a certain new and Improved Vapor-Burner;and I do hereby declare that the following is a full, clear, andcomplete description thereof, reference being had to the accompanying`drawings, `making a part of this specification, in which--4 Figure l`represents a vertical transverse Fig. 2 shows a front view of theburner. Figs. 3 and llare horizontal transverse sections taken,respectively,

" A through the lines .r l.fr and fr x.

Like letters of reference refer to like parts in the several Views.

. Ais the gasgener'ating chamber ofthe burner, arranged on one side ofthe induction gastube B, below the bottom C of the combustion-chamberl), which` bottom C' forms the top of said gas-generator, as seeninFig. 1. An interior view of the generator and the shape thereof areshown in Fig. 4, in which the broken line a indicates the heater plateor bottoni C of the combustion-chamber above alluded to. l

E is a conduit leading from the generator t to the needle-valveorificec, passing upward through the arm Fof the conduit, the needle-` iy 3o valve ed being shown in position therein, all as seenin Fig. l.`From the lower side of said arm F depends a tubular screw, G, up

through which the sternof the needle-'valve passes. The lower end ofthestem is fixed in the bottom of a socket, H, provided with an internalthread adapted to t and screw onto the tubular `screw G, operated forthat purpose, and for opening and closing the needle-` l valve by afinger-piece, I, terminating the end of the socket. It will be observedthat the said screw and socket are of `considerable length.

` `This extreme elongation of the threaded oriice is made for the`purpose t of `diminishing y the loss resulting from leakage of the oilwhen the burner 'is not lighted.`

The generator is supplied with oil through the induction-tube J and thesmall opening@ in the upperend thereof, as shown in Fig. Vl. Said tubeis an integral part ,of the generator `and conduit. Into said inductionpipe is screwed a sectional wpipe, K, from two opposite sides of whichproject, respectively, the tubular arms L and M, Figs. 3 and 4; The saidpipe K, below the tubular arms, is enlarged, as seen at N, andisprovided with an internal thread, into which is screwed the oil-supplypipe O, connecting the burner to the oil-res ervoir. (Not shown in thedrawings.)

`lo the tubular arms L M are connected, reA spectively,the cupsl? and Q,which are put in open communication therewith by openings b` and c, Fig.3. `Said openings are of small caliber, to allow avery little oil onlyto percolate through into the cups to saturate the asbestus placedtherein. That too much oil may not flow intothe cups, the openings`central depression, forming` an internal boss,

R, Fig. l, terminating near to and directly over the inductiongas-tubeBL This boss R terminates at `its lower extremity in a curvedrecess or cavity, R', the concavity having the effect of giving suchdeflection to the flame as will, in connection with the perforations andthe serrations in the burner-cap, produce the best practical results. Inthe upper part of `the cap is an annular series of holes, d, and in thelower edge of the cap is an annular series of notches, e, and throughthese orifices the jets l of flame pass when the burner is lighted. Thecap is secured to the plate by screws, which may pass through the sameand into threaded lugs, which project `from the inner surface of thecap, or, instead of this, perforations may be formed in theburner-plate-two being sufficient-on opposite sides of the same, nearthe edge thereo,f, to receive acorresponding number of pins, which,being` attached to lugs 1 on the inner `surface of the wall of theburner cap, depend therefrom and extend through these orifices; and thislatter construction is` IOO e y j essais in Fig. 3 as partly d rawnout.) The oil-satu` rated contents are then fired, the heat of whichquickly vaporizes the oil in the conduit E and arm F, at the same timeheating the oil in the generators above. .The needle-valve is thenopened and the gas or vapor ascends therefrom into thecombustion-chamber through the induction-pipe B. As the vapor issuesfrom the `perforations in the cap it burns in jets, the

heat of which is communicated by the heaterplate and cap to thegenerator, inwhich the already-heated oil is at once vaporized. Thecovers of the cups are then pushed in, thereby eXtinguishin g the amesarising from the burning oil therein. The vapor produced in thegenerator passes therefrom down the conduit to the needle-valve, andfrom thence through the tube B into the combustion-chamber, from whichit issues in burning jets, and continues to heat the generatorforvaporizing the oil therein for supplying the jets of consuming vapor.v v

The burner-cap in ordinary burners is not provided with the boss R,having the recess or cavity It', and usually'the entire space above theinduction-tube is clear, so that the vapor passes directly out of theupper perforations, and with more force and proportionate volume thanout of the lower series of perforations. This, as a consequence, causesmore heat at the top of the dome than at the bottom, where the heat ismostly needed for vaporizing the oil in the generator, as well as forother heating purposes. This defect in the ordinary burner is correctedby the boss R, provided with the deflecting-cavity R', by which, as thevapor enters the chamber, it is deiiected down upon the bottom of thechamber and issues more abundantly from the jetopenings c, causing moreheat near and about the generator, thereby facilitating thevaporiization of the oil, and at the saine time supplying the upperperforation with an abundance of vapor. j

Inhaving notches in the edge of the cap instead of perforations, insteadof orifices at a short distance above it, the ame of the jets is broughtinto immediate contact with the heater-plate, produ cing a greaterdegree of heat for heating the generator, and causing a more rapidvaporizing ofthe oil therein. Furthermore, the notches in the edge ofthe cap are made in casting the cap, thereby saving the time, labor, andexpense of drilling the holes for the jets.

In providing the cups I and Q for starting the burner, the danger isavoided of allowing a quantity of oil to run from the needle-valve `intoa drip-cup, which not unfrequently flows over the cup to the iioor,taking fire and enveloping the stove in smoke and iiame,`to the imminentdanger of the persons near by. rThe percolation of the oil into the cupsis so slow that they are not likely to overflow, but at the same time itis sufficient for the purpose required. As hereinbefore said, oil isprevented from leaking around the valve-stem by the great length of thescrew-socket andthe tubular screw through which the stem of the valvepasses, closely ftting,but free to move therein. This particular featureof the burner is not only safe against leaking, but it is simple anddurable in structure and neat in appearance.

A burner-cap provided at its base with serrations is in itself not new,yand I make no broad claim thereto.

It is apparent that the function of the central concavity is the samewhether serrations or perforations be employed at the base of the cap.

Vhat I desire to claim and secure by Letters Patent is- I f 1. Aburner-cap having within it a central downward projection, which at itslower eX- tremity is provided with a concavity, substantially as and forthe purpose set forth.

2. A burner-cap having a central recessed downward projection, a seriesof orifices near the top, and a series of orifices at the base thereof.

3. rIhe cambination of a burner-cap having a projection which isprovided with a concavity, and an upper and a lower series ofperforations, and a central vertical passage, substantially asdescribed.A l

4. The combination of the interiorly-threaded socket or sleeve H,carrying the needlevalve, and the tubular, screw or exteriorlythreadedprojection G, substantially as and for the purpose set forth.

5. In vapor-burners, the cups P and Q, pro'- vided with covers, andrespectively arranged ICO IIO

on each side of the needle-valve mechanism, and in open communicationwith the oil-supply pipe O by the intervention of the armsL and Mandperforations b and c', in the manner substantially as described, and forthe purpose set forth. f

In testimony whereof I affix my signature in presence of two witnesses.
